Quantum Snake Oil
Deterministic Chaos Encryption
Chaos-based encryption has faced published cryptographic criticism since 1989. I examine what chaotic dynamics can and cannot do for encryption, and what to ask a vendor selling it.

EMVCo Says Card Payments Are Decades From a Quantum Threat, but Its Authors Counted IBM’s Logical Qubits as Physical Ones
The card industry's technical body expects no quantum threat to EMV chips before 2040. Its new position paper is right about symmetric cryptograms, while its timeline, warning milestones and cost figures don't match the 2025–2026 record.

First Quantum-Safe Bitcoin Transaction: What QSB Proves
The first quantum-safe Bitcoin transaction was confirmed on mainnet on 26 August, built by StarkWare's Avihu Levy using hash-based constructions within existing consensus rules. The method protects individual holdings but cannot help the six million BTC with public keys already…

IBM Connected Two Quantum Cryostats. The Three Numbers That Matter Were Not in the Press Release
IBM has connected and cooled two modular cryogenic cells. Beyond the press release, its specification sheet and briefing coverage disclose 30 kW per module, 23 mK with a simulated payload, and 99.3 percent interconnect fidelity. The design also requires warming…

Harvard Extends Diamond Qubit Coherence Threefold With Sound Instead of Microwaves
Harvard researchers extended diamond qubit coherence threefold using mechanical vibrations instead of microwave pulses – addressing a compatibility problem that had blocked phonon-based quantum networking on a chip.

Sweden Publishes Its First National Quantum Strategy
Stockholm has published the document its research community asked for two years ago. The goals run a decade. The programme that built the country's quantum research base is funded for four more years. The strategy is silent on what follows.

Physicists Predict a Voltage-Free Oscillating Supercurrent in Andreev Qubits but Underestimate How Much Reading It Disturbs the Qubit
Physicists in China and Brazil predict that an Andreev qubit in superposition drives an oscillating supercurrent with no applied voltage. Their simulated readout of one qubit through that current assumes a precision that would destroy the state being read.

The GSMA’s Telco Quantum Playbook Misreports the McKinsey Report It Cites
A trade body published a vendor-contributed document, and the one exhibit anyone could verify turned out to misreport the report it names. What that costs the operators who will quote it in board papers.

Proving Your Crypto Inventory Is Complete Without Handing Over the Map
Four research teams have built privacy-preserving validation systems for bills of materials. Each can prove something about a committed record, and none establishes that the record describes the estate it claims to cover.

An Incomplete FO Check Turned wolfSSL’s ML-KEM Into Key Recovery
A researcher recovered 98% of an ML-KEM-1024 private key from wolfSSL's shipped binaries using a few hundred chosen ciphertexts. The bug was in hand-written SIMD assembly, patched in version 5.9.2.

Guarding the CBOM: The Most Sensitive Document Your Security Program Produces
Cryptographic discovery finds weaknesses that matter today, not only after a quantum computer. The resulting inventory ranks them, stays useful to attackers for years, and almost nobody has said to guard it.

The Merchant QPU Market – Who Will Actually Sell You a Quantum Processor
Strip away cloud access and turnkey machines and the number of companies that will sell a quantum processor for third-party integration drops to six. An audit of the merchant market, with prices, specs, and the gaps.

The Ethereum Foundation Spent Eight Years on a Hash Its Roadmap No Longer Needs
Binary-field proof systems made standard hashes cheap enough to prove that Ethereum's exotic one lost its reason to exist. Nobody broke it. An eight-year research bet was retired in a single post.

China Set a 420 km Quantum-Memory Entanglement Record. The Two Ends Were in One Lab.
Pan Jianwei's group heralded entanglement between two rubidium memories across 420 kilometers of fiber, published in Physical Review Letters on August 11. The concurrence at that distance sits about 2.1 times its own quoted uncertainty above zero.
